Today, The Dad took The Girl and The Boy to Schaumburg's Legoland Discovery Centre. The Boy has been begging to go to Legoland since before it opened. Allison had taken her crew to visit earlier in the fall and pronounced it a nightmare for the toddler crowd, so The Tot and I stayed home to pack, nap, and rattle around the house together.
The Dad got there at 10 a.m. when it opened and reported that the place was mobbed, with an entry line that stretched around the corner. He had a coupon for discounted entry, bringing the total for the 3 of them to $34. You can also buy tickets online for about the same price (plus a $3.75 convenience fee), which I will likely do in the future if we go again, as print-at-home tickets allow you to skip most of the entry line.
Since I wasn't there, I cannot report on the best parts of the center. However, The Boy really liked the make-your-own racecar and race-them exhibit. The Girl and The Dad liked the dragon ride. The Dad also reported that there is a cafe within the center, serving yummy sandwiches (and probably other things). Total for lunch was about $20 for the three of them, which seems about par for museum things.
